FCM net capital, funds

I've heard a lot of discussions of various FCMs, customer segregated funds, size, capital measures, etc. Only today did I found this rather useful table from the CFTC, listing all of the relevant numbers for each FCM.

I personally was surprised at how large Vision was roughly the same size as other more well-known retail firms... like IB or TradeStation. I'm also surprised how relatively small Velocity, Open E Cry, and optionsXpress are (in futures).

The seg number is for the futures side of the business. Seg funds always refers to futures. Even at that just $0.5B for a firm that is so ubiquitous and has access to virtually every futures exchange in the planet. I am very surprised.

Quote from heech:

Well, right, that's what I was really referring to.

Net capital refers to the overall size of the business + assets, and IB is understandably huge. I was more surprised by the segregated assets number, like you were.

My best guess... maybe the segregated assets number is a measure of the size of the *futures* side of the business.
